apt lists phased updates as upgradable, but an upgrade defers them until the
host is selected. A simulated upgrade names them; they are reported with the
phased flag (vantage-shared v0.6.0) and not counted in pending_after.
The window deadline no longer kills a running package manager: it only gates
the start of each phase, and a started upgrade runs under a 2 hour backstop
that sends SIGTERM on Linux. A PatchResult whose send fails is queued and
flushed on the next command stream, retaking the reboot decision. deb822
folded Suites continuation lines are filtered with the field. The startup
static inventory report is retried until it succeeds.
